-Seller net proceeds calculator for auction consignments
Use AuctionMath's seller net calculator to estimate how seller commission, insurance, photography, shipping, and additional fees affect proceeds from an auction sale. The tool helps consignors, estate professionals, dealers, and appraisers compare sale scenarios and understand how deductions can change the net amount received after hammer price.
Worked consignor estimate
On a $5,000 hammer price with 15% seller commission, $50 insurance, and $75 photography, the commission is $750, entered costs total $125, and estimated net proceeds are $4,125. Enter any applicable reserve, catalog, withdrawal, transportation, or other charges in Additional Fees, as the agreement requires.
Before comparing auction offers
Read each consignment agreement for the commission basis, minimum charges, insurance valuation, photography costs, additional fees, and whether unsold lots incur charges. This calculator subtracts the entered percentage commission and fixed costs from the hammer price; it does not account for taxes, a sliding commission schedule, negotiated minimums, or costs you leave out.
